[Class 100 (i).] Sheet separators; pile-supports.-In a blank-feeding mechanism for cup-forming machines, in which the blanks 22 are fed in succession to formers 3 by means of a feeding arm 6 to which the blanks are fed by a suction transfer block 7 fitted with pneumatic control mechanism 8, the blanks 22 are carried by a base section 21 carried by a post 23 guided in a fixed sleeve 9 and raised by the action of a spring 27 when permitted by the release of an eccentric locking disc 29 coacting with the post 23. The sheets are adapted to be raised through a gradually restricted passage formed by uprights provided with resilient means which act on the edges of the sheets. The disc 29 is mounted in a fixed sleeve 28, through which the post 23 passes, and is operated by link-mechanism and Geneva gear. The magazine for holding the blanks 22, which are shaped as segments, comprises a plurality of fixed guide arms 13, and a pair of adjustable guide arms 14 secured to a baseplate 12, and each of the guide arms 13, 14 is provided with a smooth liner plate 19 fixed to its arm at the lower end and adjustable at the upper end by a screw 20 to form a restricted passage for the upward movement of the stack of blanks. The plate 12 also carries a stop arm 16 fitted with a screw 17 for limiting the motion of the blank transfer frame 18 to which the block 1 is connected. The Geneva gearing 47, 48, Fig. 4, for releasing the locking disc 29 oscillates a shaft 38 by means of an adjustable connecting-rod 42, and to the shaft 38 is connected one member 37 of toggle levers 37, 33, connected by a link 32 to an arm on the shaft of the eccentric disc 29. The toggle arm 33 is guided by a slot in a fixed bracket 35, and a pin 36 serves as a fulcrum for the arm 33. The eccentric disc 29 acts intermittently to pull the post 23 downwards against the action of the spring 27, and when the post is released the spring raises the pile into contact with the block 7.

Abstract: 1,114,284. Ultrasonic inspection devices; ultrasonic probes. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. 3 Sept., 1965 [17 Sept., 1964], No. 37852/65. Headings H4D and H4J. In an ultrasonic pulse-echo inspection device, the active face of a transmitting/receiving transducer is partially covered by a movable mask of sound-absorbing material for varying the effective area of the active face, and hence the ultrasonic beam width, in accordance with the dimensions of a workpiece being inspected. In the embodiment of Fig. 3, a piezoelectric transducer 1 mounted on a damping block 3 is movable towards or away from a workpiece 25 (e.g. a steel billet) by a screw system 12-17. The upper (metallized) face of transducer 1 is protected from abrasion by a layer 5 of material whose thickness is approximately half a wavelength of the ultrasonic radiation and whose acoustic impedance is intermediate between that of the transducer 1 and that of a coupling fluid (e.g. water) contained in a tank 18. Rubber blocks 9a, 9b defining the mask are mounted on pivoted arms 19a, 19b and slide over layer 5, in response to movement of transducer 1, to reduce the mask aperture when small workpieces are being inspected or when accurate location of a flaw is required. The length of the coupling fluid column between transducer 1 and workpiece 25 is indicated on a scale 28 and is sufficient to ensure that the second echo from the entry face of workpiece 25 is not received at transducer 1 before the flaw echoes. In a second embodiment, a transducer having a rectangular active face may be provided with a pair of rubber shutters movable by means of a screw and nut mechanism (Figs. 1 and 2, neither shown), both transducer and workpiece being submerged in a trough of coupling fluid (water). In further embodiments (none shown), a rectangular-faced transducer may be provided with a pair of shutters moving parallel to the length of the rectangle and a pair moving parallel to the width, polygonal-faced transducers may have shutters moving in directions perpendicular to the sides of the polygon, circular-faced or oval-faced transducers may have moving shutters in the form of rings, or the moving shutters may be replaced by a series of shutters having windows of different dimensions.

Abstract: 1,243,235. Tabletting machines. KIKUSUI SEISAKUSHO Ltd. 9 Aug., 1968, No. 38075/68. Heading B5A. In a rotary table compression moulding machine for the production of tablets from powdered material, the volume of each cavity and thus the weight of each tablet is regulated by detecting the compression load upon the material at the compression station by means of a strain gauge, and using the output of the strain gauge to actuate means for lowering or raising the lower punches as they pass through feed station. In the illustrated embodiment, upper and lower punches 21 and 26, guided by cams 8 and 32, are forced together to effect the compression by means of rolls 15 and 16, the lower of which is supported by a strain gauge 19. The output from the gauge is fed via amplifier E and controller R to a motor 49 which is connected by chain 51, worm 47 and wormwheel 45 to a threaded member 39. The upper end of the member 39 carries a rail 36 over which the lower punches ride as they pass through the feeder 12. In operation, if the output from the gauge falls below or rises above predetermined limits the motor 49 is actuated to lower or raise the guide rail 36 thus increasing or decreasing the volume of the mould chambers 3.

Title: Improvements relating to cartons
IPC: B65G59/10
Filed: 1962-10-09
Abstract: 1,024,705. Handling egg cartons. PAGEDETROIT Inc. Oct. 9, 1962 [April 4, 1962], No. 38193/62. Heading B8S. Egg cartons 12 are discharged one by one from magazine 24 by the aid of four members, namely blade 34, blade 48, fingers 146 and arm 62. Initially, the stack and the lowermost carton are supported as in Fig. 4 by blade 34. As blades 34 and 48 move rightwards to the position of Fig. 5 (not shown), the stack and lowermost carton fall on to arms 62 whilst fingers 146 move downwards to bend over the edge of the lowermost carton. This displacement of the edge permits blades 34 and 48 moving in unison to move to the dotted line position of Fig. 5 ready for the separation of the lowermost carton. In the final movement, blades 34 and 48 separate from each other. This leaves blade 34 to support the stack of cartons whilst blade 48 moves downwards bringing with it the lowermost carton supported by arm 62 which moves downwards at the same time. The carton is caught between two fixed rails and discharged leaving the apparatus in the position of Fig. 4 ready for a further discharge of a carton. Operation of the discharge members, Fig. 1 and Fig. 3 (not shown).-Movement is derived from the rotation of cam 84. The movement of fingers 146 which are carried by arms 122 is derived via cam follower 140, arm 138, arm 136, rod 130. The movement of the other three discharge members is effected via rod 86 and via members 52 which are pivoted at 60 to arms 56 themselves pivoted at 58. Upward movement of rod 86 causes arms 56 to pivot about pivots 58 and at the same time members 52 are caused to move upwards whilst being influenced by followers 98 moving in fixed slots 93. The upward pivotal movement of arms 56 is transferred by arm 74, follower 72 and arm 70 to the pivotal movement of arms 62 about 66. The upward movement of members 52 effects two things. Firstly, members 52 carry blades 38 and therefore directly move said blades. Secondly, members 52 are connected by rods 106 and 104 to arms 38 pivoted at 44, said arms carrying blade 34 so that arms 52 effect also the movement of blades 34. In this way the movement of arm 62, blades 34 and 48 and fingers 146 are effected from the rotation of cam 84.

Abstract: 977,337. Valves. BOFORS A.B. Oct. 26, 1961, No. 38377/61. Heading P2V. [Also in Division F1P] In a hydraulic system in which a pump 2, Fig. 2, delivers fluid to an adjustably loaded relief valve 3 and to one or more motors 7, 8 via an adjustable pressure reducing valve 5, 6, the control member 11, 12 setting the reducing valve output pressure also sets the relief valve to deliver at a pressure higher than the working pressure of the reduction valve, whereby the relief valve unloads the pump when the reducing valve stops feeding the motor. Pump pressure at 4, Fig. 4, passes into a vertical passage 25 cutting into a bore 27 and two lower bores, only one 29 being shown, and acts via a plunger passage on the left-hand end of the plunger 32 to open a relief valve 39 against the spring 36 when it is loaded via handle 38 which also loads spring 37 to open reducing valve 40 and close relief valve 41 on plunger 33 in bore 29. Pump pressure then passes to a motor at 31 and also acts via a plunger passage on the left-hand end of plunger 33 to balance the spring loading.

Abstract: 1,158,638. Rotary fluid pumps, motors and meters. J. A. HALLIWELL, D.E. TURNBULL and A. G. READ. Aug. 29, 1967 [Aug. 27, 1966], No. 38542/66. Heading F1F. A rotary positive-displacement, fluid pump, motor or meter comprises a cylindrical member 4 rotatively mounted eccentrically upon an eccentrically-positioned rotatable driving, or power-output, shaft 5, and two further cylindrical members 6, 7 lodged between the member 4 and the inner peripheral surface of a housing 1, which surface is of circular profile, the members 6, 7 being capable of revolving in a planetary manner relative to the member 4 without slipping relative thereto and said surface so that during operation of the machine as a pump fluid is displaced by said members from an inlet port 2 to an outlet port 3. To prevent slipping, the members 4, 6, 7 and the inner peripheral surface of the housing may be furnished with gear teeth, Fig. 3 (not shown), either in the manner of conventional gears or simply at the ends of said members and in corresponding locations on said surface. To prevent the members 4, 6, 7 becoming accidentally jammed by vibration when they are stationary with their axes of rotation in one horizontal plane, Fig. 1(c) (not shown), a retractable locking-pin 10, Fig. 4, engages with a recess in the member 4, this pin being biased by a compression spring 11 so that it will retract automatically when the members are made to revolve. Retraction may be effected by pressurized fluid applied to a piston-and-cylinder unit 12 from the high-pressure side of the machine. The device may comprise two members (4a, 4b), Figs. 5(a) and 5(b) (not shown), which are rotatively mounted on a common shaft (5a) eccentrically with respect to a disc (13) on a common driving, or power-output, shaft (5), each of the members (4a, 4b) being similar to the member 4 and having rotary members (6a, 7a) or (6b, 7b), which are identical to the members 6, 7, adjacent thereto. Separate inlet and outlet ports associated with the two groups of members are connected in parallel. To prevent jamming as aforesaid and effect a more steady flow of fluid, the members (6a, 7a) and (6b, 7b) are arranged to operate in anti-phase relationship. Several machines according to Figs. 1(a) and 1(d) may be connected in parallel and have a common driving, or power-output, shaft, which machines may be arranged to operate out of phase with one another. The peripheral wall of the housing 1 may be contrived to be movable about its longitudinal axis so as to vary the circumferential spacing of the ports 2, 3 relative to each other. Movement of the said wall may be effected automatically by fluid-pressure or centrifugal action.

Abstract: 1,140,077. Magnetic recording apparatus. A. C. NIELSEN CO. 31 Aug., 1966 [22 Oct., 1965], No. 38864/66. Heading G5R. A tape recording mechanism for advancing recording tape 68 from a reel 45 to a cartridge 40 along a tape track comprises a reel spindle 44, a constant torque clutch 42 for applying a load to tape 68, a recording head 71 including a tape guide 72 which is eccentrically mounted on a crank 113 and normally projected into the tape track to lengthen the path of the tape track and retractable to shorten this path, a drive capstan 74. A pressure roller 75 is normally biased towards the drive capstan to hold tape 68 in driving engagement against the capstan, pressure roller 75 being so mounted that it may be moved away from capstan 74 to release the tape. A pressure release cam 55 is mounted on crank 113 and is pivotable between a first position projecting tape guide 72 and tensioning torque clutch 42 and a second position retracting the tape guide and releasing the torque clutch. The tape recording mechanism may be used in apparatus for monitoring television receivers. When it is desired to remove the recorded tape a knob 96 is rotated clockwise. This causes a lever 108 to be raised from a detent 98b to release the pressure between pressure roller 75 and capstan 74 and thereby free tape 68. At the same time a cam follower 110 is pivoted clockwise by a cam 99 which releases the load on torque clutch 42 and simultaneously retracts eccentric guide 72. At the same time segment 97a, Fig. 7 (not shown), of gear 97 engages a pinion 104 driving cartridge 40. Clockwise rotation of knob 96 is continued until all the tape on which recording has taken place is wound on to cartridge 40, a space 97b, Fig. 11 (not shown), on gear 97 providing a stop for cartridge 40. Knob 96 is then rotated counterclockwise and a cam 100 mounted on cam 99 causes a knife 101 to cut the tape. Continuous rotation of knob 96 in a counterclockwise direction permits capstan lever 108 to drop into detent 98b and re-apply pressure between roller 75 and capstan 74 to hold tape 68. This counterclockwise rotation restores the force to torque clutch 42 and pivots eccentric tape guide 72 into the tape path to pull a small section of tape from reel 45 thereby pretensioning the tape. A new cartridge 40 is then placed on spindle 93 to receive tape 68. A tape drive mechanism 80, Fig. 3 (not shown), is provided to advance tape 68 in a step-by-step movement.
